California Smog Help: What is the E.O. CARB number for Magnaflow cats?

[RevoGLI]

Hey guys,

Tried to get smogged today and the two shops I went to did a full visual underneath the car.

My intake has a CARB sticker with the "D-XX-X" number stamped on it, but they couldn't see anything stamped on my 42DD turboback.

My exhaust is 42DD and their website says they use a Magnaflow CA cat.

What is the E.O. number I need to use?

Probably going to have to call up 42DD and ask which one they used

If you know the EFN from the emission compliance sticker (center of front core support), you may be able to look it up here: https://www.magnaflow.com/catalytic-converters/

What's the internal diameter of this? I'm wondering how I'd make this fit on my catless 3" downpipe.

Won't the downpipe still be illegal even if thew new downpipe has a "CA" cat? You remove the first cat right after the turbo by installing an aftermarket dp. I dont think any downpipe has a carb EO#.

You are correct. There are no CARB approved aftermarket cats available for our cars. Only an unaltered stock downpipe is legal. Not every inspector even looks under the car, though technically it is part of the inspection process. If they don't look and your ODBII emissions stuff passes then you can get by with any kind of downpipe... if they don't look or don't care. The Magnaflow cat used on the 42DD is Calif approved for use on few cars just no ours.

You can't buy a general CA cat. Each model cat has to be specifically approved for use on a particular model of car. To get a CARB number for our car someone would have to pay big bucks to have it go through state testing. Since there is almost no market for the product, nobody is going to waste money on that process.
